AS-Interface Bus
The table below gives the technical characteristics of the AS-Interface bus:
Characteristic
Value
Maximum cycle time of bus: (2+n)*156 μs
where n = number of active slaves
5 ms for 31 standard or extended address setting slaves,
10 ms for 62 extended address setting slaves.
Maximum number of slaves on the bus
31 standard address setting slaves or
62 extended address setting slaves.
Maximum length of AS-Interface bus cables:
all branches without repeater
with two repeaters at 100 m and 200 m
100 meters
300 meters
Maximum number of I/O managed by the bus
Standard address setting slaves: 124 inputs +124 outputs
Extended address setting slaves: 496 inputs + 496 outputs
Nominal bus supply voltage
30 VDC
Altitude Operating Conditions
The characteristics in the table below apply to the module BMX EIA 0100 for use at altitude up to 2000 m (6560 ft). When the modules operate above 2000 m (6560 ft), apply additional derating.
For detailed information, refer to chapter Operating and Storage Conditions.
